I am considering purchasing a used Dell Lap Top which has the Windows Vista Ultimate 64bit Operating System installed.
I am not a technical wizard but understand a little of the pro’s and con’s of 32bit and 64bit versions.
However if I decide that the 64bit version is not for me (I believe that some of my older 32bit software might not work on a 64bit system) can I just reformat the hard drive and install a 32 bit version of Vista or a 32bit version of XP Pro
